Abstract

The value of data transmission over idle channels in cellular systems using frequency hopping techniques is studied. The author´s analysis indicates that, although the hopping scheme creates additional capacity, it degrades system performance due to the additional interference contributed by data transmission. In order to maintain the required performance of voice channels in cellular systems, the load on the voice channels should be reduced to minimize their interference, thus reducing the interference generated by the hopping scheme. Using a designated channel for data transmission could be a better option. This designated channel can be assigned to a voice call if the channel is idle. The voice channel will hop out of the data channel when data transmission is needed. A thorough analysis is carried out to describe the conditions needed for data transmission over cellular systems with maximum capacity and minimum interference
